As Hajj nears its climax, two million Muslims gathered at the peak of the Mountain of Mercy, Mount Arafat, for a day of prayer. It is at Mount Arafat that Muslims believe Prophet Mohammed gave his final sermon before leading his followers onto Hajj several centuries ago.

While some arrived on foot from Makkah, 15 kilometres away, others reached Mount Arafat by bus. The pilgrims camped around Mount Arafat with umbrellas to shield themselves from the heat, while volunteers handed out water bottles and food boxes.

"[It's a] feeling that cannot be described. I pray to God for the victory of all those who are oppressed," said Akram Ghannam, 45, from Syria, reported AFP News.

After sunset, the pilgrims will next head to Muzdalifah on 24 September, where they collect pebbles and carry out the stoning of the devil ritual in Mina.

Despite, a recent tragedy in Mecca's Grand Mosque, where a construction crane collapse led to 109 fatalities and over 400 people reportedly injured, nearly 1.4 million foreign pilgrims are participating in Hajj this year along with several hundred Saudis and local Kingdom residents.

Once the Hajj, which is one of the five pillars of Islam, comes to a completion, Muslims worldwide will join in to celebrate Eid al-Adha on 24 September.

Saudi authorities have remained on alert through the annual Muslim pilgrimage with reports of nearly 100,000 security personnel being dispatched to ensure smooth running of Hajj.
